Property Chains Explained UK — What You Need to Know

Property chains are one of the most stressful parts of buying a home. Here’s how to navigate them.

Understanding Property Chains

How Chains Work

First-time buyer → Sells to → Sells to → Sells to → Moves to new build
    (Start)          A          B          C           (End)

Everyone in the middle needs their sale to complete before they can buy.
